So now you have moved the goalpost to: >> There might be unfair feedback loops, but they would be effectively negligible. First of all, it is curious to me that you mention the 8x disparity in murder rate but don't mention that the violent crime survey disparity is less than 0.2x. Secondly, you just claim that the policing has nothing to do with people being arrested at different rates but do not offer any evidence. Here are the actual numbers if you really care about facts. The victimization rates are 20.5% whites vs 24.1% blacks. Less than 18% difference. On the other hand incarceration rates are 0.7% whites vs 4.5% blacks. That is more than 540% difference. This means the blacks are being arrested at about 32 times the rate at which they commit violent crimes. So your claim that: >> "we can check by looking at crime victimization surveys, which generally show the same patterns of racial disparities as arrest records" is not only ignorant and false. It is so far from the truth that it is laughable.
